INKING ARRANGEMENT FOR PRINTING-PRESSES.

Specification of Letters Patent.

iPatented Aug. 1, 1905.

Application filed May 11 1904:. Serial No. 207,451.

To all whom it may concern:

Be it known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, county of New London, Connecticut,

large sheet on a comparatively small press,

and thus increase speed and decrease cost. I have patented arrangements for accomplishing this work in various ways, one method being to have a fountain on both sides of the cylinderthat is, for each series of ink-rolls to have a fountainof its own. Another way was to allow the'ink-rol'ls on the rear side of the cylinder to be chargedwith ink from time is conducted from this cylinder to the type.

This invention is set forth in the following specification and claims and illustrated in the annexed drawings, in which Figures 1, 2, and 3 show in side elevation different positions of the inking arrangement. Fig. 4 is a front elevation of Fig. 1; Fig. 5 is a rear elevation of Fig. 1.

In the drawings is shown an impression-cylinder a and a type-bed 5. An ink-fountain roll is shown at 0.

A duct-roller a? is supported by arms 6, pivoted to lever f.

A link 9 connects lever f with lever it,

actuated by cam 71 on the shaft of the cylinder. This arrangement serves to move the duct-roll from contact with the fountainroll, Fig. 1, to the vibrator Zr, Fig. 2. This movementoccurs while the type-bed is moving from the back or delivery end of thepress to the forward end of the press. During this movement the duct-roll is brought into contact with a portion of the surface of the cylinder, Fig. 3, and at theflilfsfme time remains in contact with the roller 7:. The motion of roller k and of the impression-cylinder is at i this time in the same direction; After depositing'ink'on that portion of the cylinder which serves as an ink-plate the duct-roll or? returns from the cylinder to the position shown in Fig. 2. It remains in this position until the roll 7t, which is being driven by the action of the bed, comes to a practical stop because of the stopping of the bed. At this point roll cZ leaves roll band is brought into contact with roll 0, while duct-roll (Z has no revolving motion.

A rear duct-roll is shown at m and a vibra tor at n; The link 0, actuated by lever 9 and cam causes the rear duct-roll to leave vibrator n while the bed is moving from the rear to the forward part of the press. 110- tary motion is thus imparted to the rear ductrol'l, so that it comes into contact with the ink-surface of the cylinder while they are revolving in unison. The rear duct-roll is held into Contact with the ink-surface of the cylinder during. the stopping and reversing of the bed at the forward end of the stroke. This rearduct-roll also leaves the ink-surface of the cylinder in time to allow the impressionsurface of such cylinder to pass without touching. The duct-roller m comes into contact with the vibrator n after thetype-bed is started again on theforward stroke from the rear to the front of the press. There is thusimparted .to roller 02. the same direction which it had when roller m was in contact with it at the previous stroke of the bed. In other words, duct-roller on leaves vibrator n, comes into contact with cylinder a, leaves the cylinder,

and comes back. into contact with vibrator n; I again wlthout reversing its rotary motion.

The ink-rolls of ductor d are shown at 1" and those of ductor m at r. When the bed is at its extreme forward position, Fig. 1,'the inkrolls r do not quite pass over the type, as the back edge of the type or bed stops short or.

before passing under the rolls r. Neither do rolls r pass entirely over the type, as in its rear stroke the bed stops short of rolls 7". (See Fig. 3.) The rollers a" and r are raised from contact at the point where the bed respectively reverses. This-raising from conductor-roll and a second set of rolls permanently out of contact with the cylinder and made to receive ink from the ductor and deliver the same to the type.

2. An impression-cylinder having a distributing-surface and vibrator-roller, combined with a duct-roller made to contact with the cylinder and vibrator, a second vibrator clear of the cylinder, a second duct-roller made to ers, one of the ductor-rollers being made to convey ink to the cylinder and to some of the ink-rollers, and the other ductor-roller being made to take ink from the cylinder and convey it to other ink-rollers said inking-rollers being out of contact with the impression-cylinder.

5. A reciprocating type-bed, an impressioncylinder with ink-distributing surface or inkplate portion, a vibrator and a duct-roller made to contact with the cylinder and then to contact with the vibrator at about the moment of reverse of the bed so that said ductroller will maintain its rotary motion in the same direction.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
